You seem to have encountered either a bug in flashrom or a limit of your mainboard, but I suspect the former. A problem with nVidia chipsets is that there seems to be no public documentation about the register bits. The issue you are facing is that you have an address decoding problem: While the ROM address space of 2MB of your new chip is decoded correctly (otherwise the probe would fail, as we probe at the low end of the address space), the register dump looks suspicious: > lockbits at address=0xb7154002 is 0xff > lockbits at address=0xb7164002 is 0xff > [...] > lockbits at address=0xb7244002 is 0xff > lockbits at address=0xb7254002 is 0x0 > lockbits at address=0xb7264002 is 0x0 > lockbits at address=0xb7334002 is 0x0 > [...] > lockbits at address=0xb7344002 is 0x0 > lockbits at address=0xb734c002 is 0x0 > lockbits at address=0xb734e002 is 0x0 > lockbits at address=0xb7350002 is 0x0 The lockbits on this chip are accessed in a separate address space, called the "register space", and should never read 0xff. So it is quite likely that the reads returning 0xff are not routed to the ROM chip at all, indacting a wrongly configured decoding. Only 1MB of register space is decoded. As your chip defaults to read-only, and you have to unlock it (which flashrom tries through the register space), it will fail to unlock the areas of the flash chip having lock registers that are inaccessible to the processor. So the first half of your 2MB chip is read-only, and writing to it fails. > Any ideas? Most likely, we need to reprogram the south bridge to route a larger address space to the flash chip (just hoping that no PCI component has been mapped at that area, which is at 0xFFA00000 .. 0xFFAFFFFF for the unrouted half of the flash chip while 0xFFB00000 .. 0xFFBFFFFF) is routed to the flash chip. Please post the output of lspci -nnvvvxxx (run as root) Thanks in advance, Michael Karcher

[PATCH] ft2232_spi: fix arm-usb-ocd and arm-usb-ocd-h

[PATCH] Implement unknown Dediprog commands

Secret knowledge is cool, but public knowledge is better. Implement all Dediprog commands found in USB traces, even if their purpose is not yet known. Annotate unknown commands with info about the call sequence they are embedded in and the firmware version of the log. Add a new shutdown command for firmware 5.x.

Re: [flashrom] [PATCH] Speed up dediprog writes
by Steven A. Falco 20 Dec '11

I have just tested the following patch: http://patchwork.coreboot.org/patch/3469/ which I applied to flashrom r1472. It is fantastic! I can now program and verify a M25P16 in just 15 seconds. Every bit as fast as the Windows app. One comment about the patch. The first change (to lines 30,6) should be removed, because it adds a duplicate copy of the statement "static int dediprog_firmwareversion;" Other than that, the patch looks fine to me. Here is the bit that should be removed from the patch: @@ -30,6 +30,7 @@ static usb_dev_handle *dediprog_handle; static int dediprog_firmwareversion; static int dediprog_endpoint; +static int dediprog_firmwareversion; #if 0 /* Might be useful for other pieces of code as well. */ Therefore: Acked-by: Steven A.

[PATCH] Generic programmer registration: final part
by Carl-Daniel Hailfinger 20 Dec '11

20 Dec '11

This depends on [PATCH] Add struct flashctx * everywhere All programmer types (Parallel, SPI, Opaque) now register themselves into a generic programmer list and probing is now programmer-centric instead of chip-centric. Registering multiple SPI/... masters at the same time is now possible without any problems. Handling multiple flash chips is still unchanged, but now we have the infrastructure to deal with "dual BIOS" and "one flash behind southbridge and one flash behind EC" sanely. A nice side effect is that this patch kills quite a few global variables and improves the situation for libflashrom. Hint for developers: struct {spi,par,opaque}_programmer now have a void *data pointer to store any additional programmer-specific data, e.g. hardware configuratoin info. I'd appreciate tests for the following programmer classes: - mainboard native SPI (ICH SPI, SB600 SPI, VIA SPI) - mainboard native LPC/FWH/Parallel - mainboard native bitbanged SPI (MCP SPI) - mainboard translated Parallel (SuperI/O acts as LPC->Parallel translator) - mainboard translated SPI (SuperI/O acts as LPC->SPI translator) - serprog - external SPI (Bus Pirate/Dediprog/FT2232) - external bitbanged SPI (nicintel_spi, ogp_spi) - external LPC/Parallel (satasii, atahpt, nic3com, nicintel, ...)
